TrayTrack: An Innovative New Solution in Tray Handling

11 Sep 2013

A unique, intelligent combination of a flexible overhead conveyor system, innovative tray carriers and automatic loading and unloading stations: TrayTrack brings all filled trays automatically to the correct tray sealer. It’s your choice for perfect, labor-saving, headache free, in-plant end product logistics.

TrayTrack overview An overview of the TrayTrack system.
  • A fully automatic system to take trays from where they are filled to a remote dedicated tray sealing/wrapping and labelling area without taking up valuable floor space!
     
  • A flexible system using automatic buffers to match different size trays to multiple tray sealing/wrapping and labelling lines in the most efficient way possible, thereby making the best use of this equipment!
     
  • A system to cut costly reworking and ensure the smooth flow of product from packing through to the chill store!
     
  • A system allowing all product to be tracked and traced through to the end of the packing process, whilst at the same time giving management real-time information on the efficiency of sealing/wrapping and labelling equipment! 

How welcome would such a system be in today’s large complex portion packing operations, where product is loaded into a wide variety of trays of different materials, shapes and dimensions, where tray and label changes are frequent and where sealing/wrapping and labelling equipment downtime is an unfortunate fact of life.


TrayTrack – a truly welcome new contribution to improve processing logistics!

Enter TrayTrack!

Marel Stork Poultry Processing can now offer just such a system, already proving itself in everyday practice in one of the most demanding portion packing environments in Europe.

The innovative, all new TrayTrack system takes unsealed/unwrapped trays with poultry products from where they were loaded and distributes them intelligently over multiple sealing/wrapping and labelling lines, making the best use of this equipment and ensuring the smooth flow of product through the packaging department.

An innovative new way of using an overhead conveyor

A TrayTrack line consists of a Sigma overhead conveyor system with covered tray carriers at 12”pitch. Automatic loading stations load trays with products into the carriers of the TrayTrack line, which conveys them to automatic unloading stations, where they are unloaded onto the sealing/wrapping and labelling lines. The number of loading and unloading stations will depend on the number of packing –, tray sealing/wrapping – and labelling lines.

The system is programmed by plant management using a module of the Stork PDS-NT control system. This then runs the system automatically, directing the transfer of trays to the system and deciding when and where each tray is unloaded, its aim being to match the flow of trays as efficiently as possible to available sealing and labelling equipment.

TrayTrack’s carrier – the system’s heart

The TrayTrack carrier is the heart of the system and will handle trays in a wide variety of sizes. It has a sliding arm which moves in and out during loading and unloading. Movement of the arm is controlled by flippers mounted at each loading and unloading station and activated by the PDS-NT control system.
As the trays are unsealed at this point, the carrier has a cover to prevent contaminants falling onto the raw meat.

After production all carriers are washed and blown dry in a carrier washer installed as the last component in the line.

Trays are loaded and unloaded intelligently and automatically

A TrayTrack loading station has a buffer conveyor and loading area with rotating rollers. After filling, each tray is conveyed into the loading station’s buffer to wait for an empty TrayTrack carrier. Once the system detects an empty carrier, it moves the tray forwards onto the loading area. The station’s rotating rollers and the sliding arm on the carrier then transfer the tray onto the TrayTrack carrier.

When the system gives the signal to unload a tray at a given unloading station, the sliding arm on the carrier moves forward, pushing its tray from the TrayTrack carrier onto a belt feeding a sealing/wrapping and labelling system.

Yet more buffering capacity

It will sometimes happen that a sealing and labelling line is not available for a tray allocated to it. In this case the tray will not be unloaded but will be buffered in TrayTrack, making one or more additional circuits until the line does become available.

Better packaging room layout

With TrayTrack, tray filling, involving the handling of raw meat, and tray sealing/wrapping and labelling can be kept entirely separate, giving the advantage of one clear central tray sealing/wrapping and labelling area. Moving product between the two areas does not take up valuable floor space as this happens on an overhead conveyor system.

And full information too

Besides allowing management to program the system and then running it automatically, PDS-NT makes full tracking and tracing possible. It also gives full information on the product handled by the system and will even record sealing and labelling equipment downtime.
